UE measures bandwidth

As discussed above, the work at present hypothesis among the RAN1 is that the measurement bandwidth of mobile phone is that 1.25MHz (corresponding to 6 Resource Block) measures for carrying out in the frequency.Therefore, mobile phone 3 will be measured the default bandwidth of 1.25MHz in all cases, no matter and the bandwidth of adjacent cell how.In asking in basis, the inventor proposes just to use as possible wideer measurement bandwidth, and the necessary relevant signaling of realization this point will be discussed hereinafter.More specifically, in the present embodiment, mobile phone 3 is arranged on the maximum possible bandwidth to carry out and measures, this maximum possible bandwidth be ongoing measure at the minimum bandwidth of adjacent cell (comprising Serving cell).

Fig. 5 example illustrates two kinds of situations:

1) situation of Fig. 5 a, wherein three adjacent cells have the measurement bandwidth of different bandwidth and mobile phone corresponding to the bandwidth of the residential quarter with minimum bandwidth; And

2) situation of Fig. 5 b, wherein all adjacent cells have identical bandwidth, and this bandwidth is greater than the bandwidth of Serving cell, and wherein mobile phone 3 is carried out measurement in the bandwidth (as the minimum bandwidth in all just monitored residential quarters) of Serving cell.

Signaling mechanism

In this embodiment, serving BS 5 signaling mobile phones 3 are in the measurement bandwidth of carrying out should using when it is measured.It finishes this notice by using RRC to measure control message.In order to finish this notice, serving BS 5 must be known the bandwidth of cell of all adjacent cells, and in this embodiment, this information is stored in the neighbor cell list 39.

Initial information in the neighbor cell list 39 is normally by operation and the management (O﹠amp of network; M) function provides.Yet, along with the interpolation of new residential quarter or along with the removal of old residential quarter, adjacent cell will change often.Identified by its mobile phone of serving 3 in response to new residential quarter, these cell changes can be used automatic proximity relations (ANR) process to identify by base station 5.For example, the measurement report that receives from one of mobile phone 3 may identify the residential quarter that makes new advances (that is, not by identification of base stations and therefore do not appear at a residential quarter in its neighbor cell list 39).If so, then the base station 5 of Serving cell will detect existence by the new residential quarter of mobile phone 3 reports.In response, L3 (broadcasting) the residential quarter ID of the new residential quarter of base station 5 order mobile phones, 3 reports.In case obtained this residential quarter ID, base station 5 just uses the L3 residential quarter ID that receives to search the transport layer address (for example, IP address) of the base station 5 of this new residential quarter.Serving BS is set up then towards the new X2 interface of this base station (can not use if still there is X2 interface).In case X2 interface is established, the following information of each residential quarter that this base station is just controlled it via newly-established X2 interface sends to serving BS:

1) the 1st layer of residential quarter ID

2) the 3rd layer of residential quarter ID

3) measure bandwidth

Serving BS 5 is used its neighbor cell list 39 of new detected cell update then, and with storage with by other residential quarters of same node control relevant the 1st layer, the 3rd layer with measure bandwidth information for use in the future.This processing is illustrated among Fig. 6 by example roughly, and wherein base station 1 is that serving BS and base station 2 are that control is by the base station of mobile phone 3 detected new residential quarters.

Therefore, when reason finishes herein, neighbor cell list 39 will comprise the following information shown in the table 1:

Table 1

The maximum that the mobile phone 3 that serving BS 5 uses the bandwidth information in the neighbor cell list 39 to determine that it is served then should be measured is measured bandwidth.This information is given mobile phone 3 by signaling then in measuring control message, measure control message at this, and measurement is established subsequently in the frequency.Will be understood that as those skilled in the art when identified and its bandwidth was added to neighbor cell list 39 when new residential quarter, this may cause base station 5 to reconfigure the measurement bandwidth of the mobile phone 3 that it serves.By this way, base station 5 dynamically defines the measurement bandwidth of the mobile phone 3 that they serve.

White list

Adjacent cell information 39 will comprise white list and blacklist.Can for mobile phone 3 to the residential quarter of its roaming on white list, simultaneously, disabled or not by those residential quarters of Network Recognition on blacklist.When determining the measurement bandwidth that will be used by mobile phone 3, base station 5 will only be finished definite based on the known bandwidth of the residential quarter in the white list.

Will be understood that as those skilled in the art, when initially setting up, do not provide under the situation of bandwidth information in operation and management function that base station 5 can be found out this information and upgrade its database with the bandwidth information that receives by the X2 public message.(this is for the ordinary signaling of only upgrading BW information, and never calls the ANR function).This processing is exemplified in Fig. 7.Subsequently, detect if new residential quarter (belonging to base station 3) is moved phone 3, then base station 1 can utilize the ANR function to search to obtain by the cell information of the residential quarter of base station 3 controls and add these cell informations.

One of advantage of this layout is base station 5 when mobile phone 3 sends report at other residential quarters that belong to same base station 5, has had the mapping between the 1st layer of residential quarter ID and the 3rd layer of residential quarter ID.Therefore, mobile phone 3 does not need to read the BCH of the new residential quarter that belongs to known base station.Another advantage is that all information about all residential quarters of base station 5 can be provided in an X2 public message.

Revise and replace

Detailed embodiment has more than been described.Will be understood that as those of skill in the art, can make multiple modification and replace and still to have benefited from the invention that comprises at this simultaneously above-described embodiment.Only as illustration, these some in substituting and revising will be described now.

In the above-described embodiments, telecommunication system based on mobile phone has been described.Will be understood that as those of skill in the art the signaling of Miao Shuing and handoff techniques can be applied in any communication system in this application.Particularly, many in these handoff techniques can be used in or use electromagnetic signal or use acoustical signal carry data based in the wired or wireless communication system.In the ordinary course of things, base station and mobile phone communication node or the equipment that can be regarded as communicating with one another.In the handover, the source and target communication node will be formed by each scheduling entity in the base station in eNodeB.Other communication nodes or equipment can comprise the subscriber equipment such as for example personal digital assistant, laptop computer, web browser etc.

In the above-described embodiments, some software modules have been described.Will be understood that as those of skill in the art, software module can with through compiling or provide without the form of compiling, and can be supplied to base station or mobile phone as signal via computer network or on recording medium.In addition, can utilize one or more special hardware circuits to carry out by the function of part or all execution of these softwares.Yet it is preferred using software module, because it is conducive to the renewal of base station 5 and mobile phone 3 so that its function is upgraded.

----------------------------------------------------------

Introduce

Work at present hypothesis among the RAN1 is that the measurement bandwidth of 1.25MHz (6RB) will be used to carry out measurement in the frequency.Yet we believe if UE can go up at maximum possible BW (for example 10MHz) but not use the default BW of 1.25MHz to carry out measurement under whole adjacent cell has more than or equal to the situation of the BW of 10MHz, will be useful so.

In this document, we discuss the mechanism that relates to when determining maximum possible BW, and on this maximum possible BW, UE can carry out RSRP and rssi measurement to adjacent cell.

--------------------------------------------------------

Discuss

Based on the current hypothesis of RAN1, UE will measure the default BW of 1.25MHz in all cases, no matter and the BW of adjacent cell how.In this document, the signaling that our suggestion just uses wideer measurement bandwidth and discussion to be associated as possible.

The situation 1 of Fig. 8 illustrates such situation: wherein show three adjacent cells with different B W.UE should carry out measurement by the minimum BW in adjacent cell.In situation 2, all adjacent cells have such as the identical BW of 20MHz, however Serving cell BW such as be 10MHz, and for relatively Serving cell and adjacent cell signal strength signal intensity, UE should carry out at the BW of 10MHz and measure so.

4.1. signaling mechanism

Give UE in order to utilize RRC to measure control message with measurement BW signaling, propose that eNB safeguards the bandwidth of cell information that it is relevant for each residential quarter in neighbor cell list.

Scan referring to the mechanism among Fig. 9:

For the residential quarter in the white list, eNB or pass through O﹠amp; M (Figure 10) in case or X2 connect just to be established and obtain the information relevant with measuring bandwidth by being close to eNB via X2 (Figure 11).

For by the new residential quarter of adding of ANR (proximity relations automatically) function, obtain the measurement bandwidth information via the X2 public message.

By using this mechanism, the maximum that eNB can use adjacent cell BW information to determine that UE should measure is measured BW.Measure and control in the message by signaling in measurement when BW can measure in setting up frequency then.ANR mechanism has been described in [R3-071819].This machine-processed summary is reported as follows:

1.UE send the measurement report of the signal strength signal intensity of detected residential quarter.This report comprises the 1st layer identifier of detected residential quarter.

2. if service cell eNB detects existence and is reported as neighbours' new residential quarter by UE, it will:

A. order UE report L3 residential quarter ID

B. utilize L3 residential quarter ID to find the transport layer address of new eNodeB

C. if desired, then set up new X2 interface towards this eNodeB

D. upgrade its proximity relations tabulation.

This mechanism has also been optimized ANR mechanism, and is as follows:

In case the x2 that has set up towards a certain eNB owing to the ANR function connects, new neighbours eNB just sends the following information relevant with the residential quarter of its control via newly-established X2 interface:

The 1st layer of residential quarter ID

The 3rd layer of residential quarter ID

Measure bandwidth

The result:

When eNB sends measurement report at other residential quarters that belong to same eNB at UE, had the 3rd layer of residential quarter ID mapping of the 1st layer of residential quarter ID-.Therefore, UE does not read BCH in the case.

Only need X2 public information of each eNB.

------------------------------------------------------

Conclusion

In this document, we have proposed in the simple mechanisms of determining that UE thereon relates in the time of can carrying out the maximum possible BW of RSRP and rssi measurement to adjacent cell.Rssi measurement will have benefited from more wide bandwidth certainly, yet the benefit of measuring for RSRP also requires further study.

This mechanism and 2/ stages 3 of update stage standard correspondingly propose to be discussed.

In this please based on and the British patent that requires to submit on October 29th, 2007 in please No.0721155.0 priority, the full content of asking in this British patent is incorporated into this by reference.
